Abstract: The present invention relates to novel metathesis catalysts with an imidazolidine-based ligand and to methods for making and using the same.

Abstract: The invention pertains to the use of Group 8 transition metal carbene complexes as catalysts for olefin cross-metathesis reactions. In particular, ruthenium and osmium alkylidene complexes substituted with an N-heterocyclic carbene ligand are used to catalyze cross-metathesis reactions to provide a variety of substituted and functionalized olefins, including phosphonate-substituted olefins, directly halogenated olefins, 1,1,2-trisubstituted olefins, and quaternary allylic olefins. The invention further provides a method for creating functional diversity using the aforementioned complexes to catalyze cross-metathesis reactions of a first olefinic reactant, which may or may not be substituted with a functional group, with each of a plurality of different olefinic reactants, which may or may not be substituted with functional groups, to give a plurality of structurally distinct olefinic products.

Abstract: The present invention relates to novel metathesis catalysts with an imidazolidine-based ligand and to methods for making and using the same. The inventive catalysts are wherein: M is ruthenium or osmium; X and X1 are each independently an anionic ligand; L is a neutral electron donor ligand; and, R, R1 R6, R7, R8, and R9 are each independently hydrogen or a substituent selected for the group consisting of C1 C20 alkyl, C2-C20 alkenyl, C2-C20 alkynyl, aryl, C1-C20 alkoxycarbonyl, C1-C20 alkyithiol, aryl thiol, C1-C20 alkylsulfortyl and C1-C20 alkylsulfinyl, the substituent optionally substituted with one or more moieties selected from the group consisting of C1-C20 alkyl, C1-C10 alkoxy, aryl, and a functional group. The inclusion of an imidazolidine ligand to the previously described ruthenium or osmium catalysts has been found to dramatically improve the properties of these complexes.
